England's Brian Davis topped the qualifiers for the Open Championship after a six under par round of 64 at the Gleneagles Club in Plano, Texas as Sergio Garcia was forced out with an infected fingernail.

Davis finished one shot ahead of American Chad Campbell as heavy rain forced the International Final Qualifying - America event to be reduced from 36 holes to 18.

No longer exempt after falling out of the world's top 50, Garcia was on level par when he quit after four holes.

He then explained on his Twitter site: "Unfortunately had to wd from qualifier this morning because of an infected fingernail in my left hand. Couldn't hold the club comfortably."

Runner-up to Padraig Harrington at Carnoustie four years ago after bogeying the final hole and then losing a play-off, the 31 year old Spaniard could still make it to Sandwich in July through upcoming events.

But now 73rd in the world - he was second behind Tiger Woods just over two years ago - he has also entered a qualifying event in Memphis on June 6 for the US Open the following week.

Joining Davis and Campbell in July will be Australia's Nathan Green who shot a 66, a score matched by Americans Davis Love III, Spencer Levin, Chris Tidland and Bob Estes.

The final spot on offer went to a play-off between Americans Justin Hicks and Jerry Kelly who both shot 67s.
